The University of Minnesota researchers who have stirred up the kernel community with various
types of bad patches have sent
an open letter to the linux-kernel list. “This current incident
has caused a great deal of anger in the Linux community toward us, the
research group, and the University of Minnesota. We apologize
unconditionally for what we now recognize was a breach of the shared trust
in the open source community and seek forgiveness for our missteps.“
